3 Claims.

, Prior to streamlining of locomotives the conventional location of the headlight generator was on the top of the boiler, and to serviceit the employee was obliged to climb up on the locomotive.

v With the advent of streamlining locomotives it became necessary to .remove the headlight generator from its conventional position so as to maintain, without a break, the streamline contour of the streamlining cowling.

Myg'invention consists not only in relocating the said generator on the locomotive but it goes.

further in providing means for supporting the said generator in a position on the locomotive whereby it is more readily accessible for maintenance and inspection by an employee standing on the ground beside the locomotive in which position the employee is not subjected to the intense heat from the boiler and as a result of this it has been found that the inspections have been .more thorough. My invention consists further. in providing the generator support with a shield to protect the generator from ice, snow, etc., thrown up from the right-of-way. Preferably the generator is positioned on the right side of the locomotive directly behind the rear driving wheel.

Figure 1 is a perspective View of a portion of a locomotive provided with my invention.

Figure 2 is a perspective view of a portion of the front end of the locomotive.

Figure 3 is a transverse vertical section showing the shelf supporting the generator together with the boiler and smoke stack and a portion of the cowling.

The locomotive is provided with a streamlining cowl A extending from the bottom of the pilot to the cab as shown which is not described in detail herein-because it constitutes the subject matter of another application for patent.

The reference numeral l designates a locomotive having a suitable frame 2 to which is attached in any suitable manner a headlight generator including a shelf support 3, and it is positioned, preferably on the right hand side of the locomotive directly in the rear of the rear driving wheel 4. This support comprises a bracket arranged to bear against the outer side of the adjacent frame bar and having inwardly extending upper horizontal hanger arms 5, resting on and secured to said bar and outwardly lower horizontal arms 6 which support the shelf 3. The headlight generator shelf 3 rests on and is suitably secured to these supports 6 and terminates at its front end in an upwardly and forwardly extending guard shield or fender 3' which faces the wheel 4 and is disposed between said wheel and the generator and serves to protect the generator from snow, ice, etc., which may be picked up from the right-of-way.

5 The. headlight generator I is directly coupled with the shaft of the steam turbine l. The turbine l is provided with an exhaustpipe 8 which extends upward under the streamlining cowling next to the boiler and terminates at its 10 upper end in the smoke stack 9. That portion of the exhaust pipe 8 in the smoke stack, and between the boiler and cowling is subjected to intense heat which causes the pipe to expand and when cool to contract, which is a condition not heretofore experienced, therefore I provide an expansion joint 8' between the generator and the generator exhaust pipe 8.

The generator is connected by means of the cable I!) to the headlight ll.

As stated the streamlining of locomotives presented many problems to be solved in maintaining the streamline effect by repositioning various parts that heretofore had been on top of the boiler, without affecting the efiiciency of. such parts and the resultant functioning of the locomotive and my problem was with reference to the headlight generator. After considerable experiments I found that the positioning of the generator as herein disclosed that due to its height from the ground, and absence of heat in the vicinity of the generator the maintenance and inspection of this generator was very materially improved, which resulted in an improved operation of the generator and head. light.

Itwill be observed that the generator is arranged to lie just inside the vertical plane of that portion of the side wall or side panel of the streamline cowling which covers the side of the boiler in rear of the wheel 4, which side wall or panel is arched or arcuately cut away at its lower edge from a point just in rear of the rear driver wheel 4 to a point in advance of the front driver wheel in order to expose and allow free access to the drive wheels. A cowling with side panels of this type is shown for example in Lentz Patent No. 2,119,082. That part of the panel which lies just outside the generator extends downward to a level close to and just above the level of the top of the generator and forward to a point about in line with the vertical center of the generator, from which point the arched portion of the paneling begins and continnes forwardly to a point in front of the front driver wheel. The generator is thus partially overhung by a portion of the cowling and partially exposed below the level of the cowling and in the space between the first-named part of the cowling and the wheel 4 beneath the adjacent arched portion of the coWling. By this arrangement the generator and associated working parts are sufficiently exposed to allow access thereto for the purpose of making repairs, etc., while at the same time the connections to the generator are concealed from direct view and the generator largely protected by the panel, shelf and guardfender from damage by flying missiles thrown up from the road bed by the action of the locomotive wheels.

What I claim is:

1. In a locomotive, the combination with a locomotive frame, a rear driving wheel, and Smokestack, of a streamlining cowl for the boiler having a vertical panel spaced rearwardly from the driving wheel and lying outwardly beyond the vertical plane thereof, a bracket secured directly to a side of said frame and projecting laterally therefrom in rear of the drive wheel, a horizontal shelf carried by the bracket and arranged below and substantially on the inside of the vertical plane of the panel and partially projecting into the space between the panel and the driving wheel, a headlight generator secured to said shelf, a guard fender projecting toward the driving wheel at an upward and forward angle from the shelf in front of the generator, a turbine secured to said shelf and operating to drive the generator, and an exhaust pipe for the turbine lying inside said cowli-ng and alongside the boilerand discharging into the smoke stack.

2. In a locomotive, the combination with the locomotive frame, boiler, and a rear drive wheel,

'of a streamlining cowl for the boiler having a side panel depending to a level corresponding substantially to the level of the axle of the drive wheel and cutaway to leave a space between the same and the drive wheel, a bracket secured directly to the adjacent side of said frame and projecting laterally therefrom, a shelf supported by the bracket'inrear ofthe drive wheel substantially on the inner side of the vertical plane 'of the panel and projecting partially beneath the cowling and partially into said space, a guard fender extending at an upward and forward angle from the front of the shelf toward the drive wheel, a headlight generator secured to said shelf in rear of the guard fender, a turbine secured to said shelf and driving the generator, an exhaust pipe for the turbine extending under said cowling and alongside the boiler and discharging into the smokestack, and an expansion joint in said pipe to compensate for expansion and contraction of said pipe, said shelf being accessible from the outside of the locomotive frame and arranged at an elevation substantially in the horizontal plane of the driving wheel axle.

3. In a locomotive, the combination with the locomotive frame, boiler, smokestack, and a rear driving wheel, of a cowling for the boiler having a side panel depending to a level corresponding substantially to the level of the axle of the drive wheel and cutaway to leave a space between the same and the drive wheel, a bracket supported from one side of the locomotive frame adjacent to the driving wheel and in a horizontal plane adjacent to but below the level of the horizontal plane of the driving wheel axle, a shelf supported by the bracket substantially on the inner side of the vertical plane of the panel and projecting substantially beneath the cowling and partially into said space, a generator mounted on said shelf substantially in the horizontal plane of the driving wheel axle, a turbine supported by the shelf for driving the generator, a guardfender extending in front of the generator from the front of the shelf at an upward and forward angle toward the driving wheel, and an exhaust pipe leading from the turbine motor upwardly inside the cowling and extending alongside the'boiler and arranged to discharge into the Smokestack said shelf and bracket being located at the rear of the driving wheel between the wheel and the depending cowling.
